A measuring apparatus includes an acoustic transducer with a plurality of elements, each element detecting an acoustic wave generated from a sample and converting the wave into an electric signal a movement control unit which moves the acoustic transducer from a first position to a second position and a processing unit which generates image data on the basis of the electric signal. The acoustic transducer has a gap in the arrangement of the elements. The acoustic transducer detects an acoustic wave at the first position, is moved by the movement control unit such that the position of the gap at the first position corresponds to the position of the element at the second position, and then detects an acoustic wave at the second position. The processing unit generates image data on the basis of electric signals obtained at the first and second positions.
